I have a diagram similar to the following. Water entering the larger end is at 20degreesC.

+ ∗∗+ /∗∗ = t

p1 - p2 = density/2 (v2 ^2 - v1^2)

P = F/A

A1V1 = A2V2

I have calculated the pressure at the smaller end using P=F/A . P2 = 12..3N/cm2

Using A1V1 = A2V2 I know that V2 = 7.11 * V1

I have inputted my values in the Bernoulli Equation p1 - p2 = density/2 (v2 ^2 - v1^2) , however I am ending up with both velocities as unknowns and also P1 is unknown.

I am getting stuck when I come to calculate Pressure at point 1 and Velocity at Point 2.

Any pointers or suggestions would be appreciated.

- The larger end has a diameter of 8cm and Area 50.26cm2.
- The small side has a diameter of 3cm and Area 7.0685cm2.
- The water jet exerts a force of 87N on a flat plate at an unknown distance.
- Assuming no frictions and a steady flow

- Liquid is water
